This invention relates to an elevator suited for instance for the loading and unloading of ships as well as for any transport or holstlng of various granulous or powdery materlals.

One object of the invention is to secure an apparatus of hermetically closed construction having the shape of a flexible pipe, consequently capable of being displaced at all points of its zone of operation and of efiecting the transport of the granulous materials eventually charged with dust without any loss, in a continuous manner and at high working speed whilst still eventually allowing the dust to be separated when working as sucker.

With this object in view the invention essentially consists in the special arrangement and combinations of parts as hereinafter fully described and pointed out 1n the ap- 2 pended claims.

The accompanying drawing shows by way of example a construction according to the invention.

Fig. 1 gives a view in slde elevation, partly in section of a portion and of a oint, the

plane of the sectionof the first compartment to the left of the portion being 1n d1- cated by the line 11, the second to a sect on taken through the line 11 and the third to a section taken through the line 11 in Fig. 2.

Fig. 2 gives a plan view of the whole with horizontal section through the first compartment and plan view of the two following drums, the cover being removed.

Fig. 3 gives at an enlarged scale a cross section of the portions of ]O1D1JS showing tne flexibility; this figure reproduces the different sections shown in Fig- 1.

Fig. l gives also at an enlarged scale a longitudinal section of a portion of oint taken through the line l l in Fig. 3.

Fig. 5 shows at the same scale a horizontal section of a portion of art1culat1on taken through the line 55 in 1g. 3.

Fig. 6 gives a view in side elevation of the jointed portions without the series of gear ings. I

Fig. 7 shows an example of application of such an elevator.

As shown in Figs. 1, 2, and 7, the apparatus is formed ofa rigid portion assembled with jointed portions 2 so as to have a certain mobility enabling certain portions to occupy an angular position in relation to the others.

The fixed portion is formed of two parallel walls 3 assembled by means of bolts 4:. The walls 3 are provided on the sides facing each other with curved grooves 5 in which are fitted two metal sheets 6 and 7 having a curve of the kind shown in Fig. 1. These metal sheets 6-7 consequently form a series of chambers 8 communicating with each other by passages 9. The chamber situated at the end of the last portion is open at its end at 10 (Fig.1).

In the parallel walls 3 openings 45 are provided arranged excentrically with respect to the chambers 8 formed by the curved metal sheets 6 and 7 in which are housed sleeves 11. fixed in the walls 3 by keys 12 (Fig. 4) and nuts 13' provided with felt washers 1%.

The sockets 11 receive ball bearings 15 in which rotate shafts 16 maintained by abutments 17 and spacing members 18. On the shafts 16 are mounted by the squares 19 wheels or drums 20 comprising side cheeks 21 connected by ribs forming semicylindrical recesses 22. In each semicylindrical recess of the drums 20 is mounted a paddle or vane 23 passing through the cheeks 21 by a shaft end 24 carrying a chain-wheel 25 over which passes a chain 26 partly surrounding the wheels 25 of the three or several vanes 23 of one drum 20 and on the other hand containing a cog-wheel 27 formed on the inner end of each of the sockets 11.

On the side cheeks 21 are mounted protecting covers 28 provided with vanes 29 for driving the grains from the walls 3. Each protecting cover 28 serves as oil-chamber for lubricating the internal mechanism and is providedwith a felt washer 30 to prevent the passage of the dust and with a joint 31 to secure from leakage. Beyond the nuts 13 the shafts 16 carry at each end a toothed wheel 32 gearing with the toothed wheel 32 of the shaft 16 corresponding to the next drum 20. All of the toothed wheels 32 are covered by a casing of stamped sheet metal 33 (Fig. 2) held away from the walls 3 by tubular eyelets 34 surrounding the ends of the bolts 4 so that the whole transmission is practically protected by a cover. At the place of the joints 2 the walls 3 are interrupted and the continuity of the casing is ensured by an auxiliary casing 35.

Each jointed portion 2 is composed of two chambers formed partly by the curved sheets of metal 6 and 7 fitted in the grooves 5 of the walls 3 and by auxiliary casings 35. In the walls 3 are mounted centrally with the chamber 8 two sleeves 11 similar to the sleeves 11 above described, but provided with discs 11 fitting in the corresponding openings of the walls 8 (Fig. 4, lower part).

lVhen the, device is working, if the elevator is assumed to be thus formed of a number of portions and if one of the toothed wheels 32 is started rotating by a suitable motor, all of the toothed wheels of the different portions will be set in rotation in the direction of the arrows in Figs. 1 and 3. Under these conditions the shafts 16 in rotating drive the wheels or drums 20 and set in rotation the vanes 25 in the semi-circular recesses 22 of each of the drums so that the chains 26 roll over the fixed pinions 27 formed by the sockets 11 and 11. Consequently, if the open end 10 of the endmost portion is plunged into a granular matter, this granular matter will to some extent be shovelled up by the rotary vanes 23 and will be driven first into the first chamber 8 in order to pass it through the opening 9 into the second chamber 8 where it will again be picked up by the vanes of the drum rotating in this chamber and so on to the other end of the elevator where it can be unloaded in any suitable place. The apparatus being leakage-proof the transport will be effected without loss, without producing dust, and owing to the relative flexibility of the different portions it will be possible to have the elevator travel into any places desired without being-obliged to resort to auxiliary apparatus of great mechanical complication.

By way of example Figure 7 shows the use of a similar elevator with a View to un loading a ship.

As this figure shows, the whole of the elevator designated 39 starts freely in the hold 40 of the ship and is actuated by any motor 41 engaging by means of a belt 42 a pulley mounted at the end of one of the shafts 16. The elevator can be be bent sideways so as to discharge into a hopper 43 the matter taken out of the hold of the ship and to allow this matter to be poured into barges or lighters 44. Owing to the mobility of the elevator 39 the latter can be successively brought at all points to the hold, as shown by the tracing in dotted lines.

As will be easily understood the apparatus thus constructed is of a specially economical construction whilst still ensuring a more considerable output and an easier manipulation than the hitherto used apparatus designed for the same purpose.

What I claim is:

1. In a flexible elevator in combination jointed portions comprising each a number of chambers, drums rotatably mounted in the said chambers, each drum being provided with semi-circular cavities, vanes rotatably mounted in the said cavities and means for rotating the drums and vanes whereby a granulous matter shovelled by the vanes is carried from one chamber to the other.

2. In a flexible elevator in combination a rigid portion, a multiplicity of jointed portions, a number of chambers formed in the said rigid and jointed portions, the said chambers communicating with each other, a;

ties, a vane mounted on the said shaft, a single gearing whereby the several drums are simultaneously rotated and means whereby the vanes are rotated in the cavities of the rotating drums.

4. In a flexible elevator, a multiplicity of' portions, each comprising two chambers, a drum excentrically mounted in each of the said chambers, semi-circular cavities formed in the said drums, a vane rotatably mounted in each of the semi-circular cavities, meansfor rotating all the drums and vanes conointly, and jointed casings whereby the several portions are jointed together.

In testimony whereof I have aflixed my signature.
